Unagi = Relaxed Awareness

We make fun of Ross, and his state of Unagi, but Scott Stewart of STRATFOR talks about 'relaxed awareness' in terms of spotting dangerous situations in our personal lives, and in our national security.

"A Primer on Situational Awareness:


By Scott Stewart
The world is a wonderful place, but it can also be a dangerous one. In almost every corner of the globe militants of some political persuasion are plotting terror attacks — and these attacks can happen in London or New York, not just in Peshawar or Baghdad. Meanwhile, criminals operate wherever there are people, seeking to steal, rape, kidnap or kill.
Regardless of the threat, it is very important to recognize that criminal and terrorist attacks do not materialize out of thin air. In fact, quite the opposite is true. Criminals and terrorists follow a process when planning their actions, and this process has several distinct steps. This process has traditionally been referred to as the “terrorist attack cycle,” but if one looks at the issue thoughtfully, it becomes apparent that the same steps apply to nearly all crimes. Of course, there will be more time between steps in a complex crime like a kidnapping or car bombing than there will be between steps in a simple crime such as purse-snatching or shoplifting, where the steps can be completed quite rapidly. Nevertheless, the same steps are usually followed.
People who practice situational awareness can often spot this planning process as it unfolds and then take appropriate steps to avoid the dangerous situation or prevent it from happening altogether. Because of this, situational awareness is one of the key building blocks of effective personal security — and when exercised by large numbers of people, it can also be an important facet of national security. Since situational awareness is so important, and because we discuss situational awareness so frequently in our analyses, we thought it would be helpful to discuss the subject in detail and provide a primer that can be used by people in all sorts of situations.

Foundations

First and foremost, it needs to be noted that being aware of one’s surroundings and identifying potential threats and dangerous situations is more of a mindset than a hard skill. Because of this, situational awareness is not something that can be practiced only by highly trained government agents or specialized corporate security countersurveillance teams. Indeed, it can be exercised by anyone with the will and the discipline to do so.
An important element of the proper mindset is to first recognize that threats exist. Ignorance or denial of a threat — or completely tuning out one’s surroundings while in a public place — makes a person’s chances of quickly recognizing the threat and avoiding it slim to none. This is why apathy, denial and complacency can be (and often are) deadly. A second important element is understanding the need to take responsibility for one’s own security. The resources of any government are finite and the authorities simply cannot be everywhere and cannot stop every criminal action. The same principle applies to private security at businesses or other institutions, like places of worship. Therefore, people need to look out for themselves and their neighbors.
Another important facet of this mindset is learning to trust your “gut” or intuition. Many times a person’s subconscious can notice subtle signs of danger that the conscious mind has difficulty quantifying or articulating. Many people who are victimized frequently experience such feelings of danger prior to an incident, but choose to ignore them. Even a potentially threatening person not making an immediate move — or even if the person wanders off quickly after a moment of eye contact — does not mean there was no threat.

Fuel Pump Protection

FYI: In order to help your in-tank gasoline fuel pump to have adequate cooling and not to suffer damage, try to run on the top half of the tank.  If the distance to payday is just too great, run above 1/3 or even 1/4 full.

Pump replacement is not easy, or cheap, and pumps not only need adequate suction head (gas level in the tank) in order to operated without damage, but they use the gasoline to cool the motor.

DIY Mopeds

In a couple of earlier posts (Bike Trailers, More Bike Trailers, Electric and Cargo Bikes, and Sport Utility Bicycles ) I  wrote about ways to make your bicycle more than just a machine for the occasional spin around the block.  A couple of days ago I ran into a site that sells small 2 and 4 cycle engine kits to make your bike into a mo-ped.

These conversions are not nearly as expensive as an electric motor and battery system would be, and look like so much fun that I'm thinking hard on getting one.

Legally (in Utah), motorizing a bicycle requires that you have a motorcycle endorsement on your drivers license.... and I have no idea whether or not you would need to register it as a motor vehicle or not....I'm thinking they probably wouldn't make a big deal out of it unless you went into the bike-to-moped conversion business.

Here is the engine buyer's guide page.... the 4 stroke 49 cc engine kit looks the best to me.  Not that I don't have enough to do already.  I just don't know if I will be able to resist. 



Have fun.  There is a ton of information on these....I had no idea.  Also, look at motorbicycling.com - they have a discussion forum with a lot of information.

Buying a Right Sized Generator

All of us have had the experience of having the power go out. This summer we had a short outage of an hour or so. One minute Annie was sewing, the lights were on, the computers were on and the TV might have been on as well. The next minute - Nada. The house was dark, the sewing machines were off, the computers were dark and quiet. I think I might have been working on supper, but with no stove, that quickly came to a halt. We wandered around for a while, wondering what had happened, and when the power would be restored.

After a few minutes I saw a neighbor who has a police/fire/emergency scanner, and who's husband is a Deputy Sheriff - she often knows what is going on. She said that a fire in a neighboring town had burned down a half a dozen power poles, and it would be Monday before they got them repaired. My conclusion was that it might be Monday (it was Saturday afternoon) before we got our power restored. I don't know how long it took to actually fix the poles and line, but they were able to re-route power to town in an hour or so, and we went back to normal living.

But I have pondered that all winter long. Every time I put a log on the fire, or turned on the furnace I thought - what would we be doing if we didn't have power. If for some reason, in the middle of the winter, we lost power it would be a pretty dark and cold house. If we didn't get it back in a day or two, I would be draining the waterlines and the water heater - you don't want to think of the pipes freezing in your walls, breaking in several places, and then soaking your house down when the power came on, and things warmed up a little. We are fairly lucky to have most of our pipes in the interior walls. We can easily let our house temperature go to 45 or probably even 35 before we would worry too much about frozen pipes. Some of my friends aren't so lucky, and in their new homes, they have all the pipes routed in their outer walls.

Summer time is easier - maybe not too comfortable, but we could probably find a way to can/bottle most of the food in the freezer if we couldn't run the refrigerator/freezer.

So these musings led me to the KSL Classifieds and the search for a generator. I quickly found that there is a huge variety in generators, and they vary widely in price as well. I worked through a lot of scenarios of how much load we would need/want and confused my self some in the process, but finally came to a conclusion, at least about how to calculate the load.

Load, or watts are found by multiplying amps x volts. We are only calculating load for 120 volt loads, so that makes things a little simpler. I don't know how much load my furnace takes, or my water heater, but I know they have run for years on a 15 amp breaker. So I know they are less, and probably quite a bit less than 15 x 120 or 1800 watts. Because they have motors in them, I'm going to leave the estimate at 1800 for extra safety when starting. Motors draw extra current when they start. The bigger the motor, the bigger the power spike.

I know that everything in my list will run on 15 ampss, as they have for years. So they are not tripping the breakers, and hopefully the generator motor will take the load. Here is my little worksheet. There are three scenarios here.

  1. I've got to have everything on the list running all the time.
  2. OK, I can do some trading of loads to buy a smaller and cheaper generator.
  3. Economy - only the essentials. But I can still trade one for the other. Cheapest option.



Generator Scaling Worksheet




Winter - Gotta Have It All Mode

Furnace 15 x 120 = 1800 watts
Water Heater 15 x 120 = 1800 watts
Wood Stove Fan 15 x 120 = 1800 watts
Freezer 15 x 120 = 1800 watts
Refrigerator 15 x 120 = 1800 watts

Total 9000 watts = 9 kw

Summer

Whole House 15 x 120 = 1800 watts
Swamp Cooler 15 x 120 = 1800 watts
Freezer 15 x 120 = 1800 watts
Refrigerator 15 x 120 = 1800 watts
Water Heater 15 x 120 = 1800 watts

Total 9000 watts = 9 kw



Can Get By With A Little Less

Winter

Furnace or Water Heater 15 x 120 = 1800 watts
Wood Stove Fan 15 x 120 = 1800 watts
Freezer or Refrigerator 15 x 120 = 1800 watts

Total 5400 watts = 5.4 kw

Summer

Whole House or Swamp Cooler 15 x 120 = 1800 watts
Freezer or Refrigerator 15 x 120 = 1800 watts
Water Heater 15 x 120 = 1800 watts

Total 5400 watts = 5.4 kw


Winter - Economy Mode

Furnace or Water Heater or
Freezer or Refrigerator
15 x 120 = 1800 watts

Wood Stove Fan
15 x 120 = 1800 watts

Total 3600 watts = 3.6 kw

Summer - Economy Mode

Whole House or Swamp Cooler or
Freezer or Refrigerator or Water Heater
15 x 120 = 1800 watts


Total 1800 watts = 1.8 kw


Annie will probably note that I don't have the hair dryer and curling iron on the list.... but they can be traded, and she is always beautiful anyway. So there you have it. You can get a 3.6 kw generator for a few hundred dollars, probably about the price of a new iPod or Blackberry. But seriously, if you need it, there will be very few things you would trade for it. More later on this adventure.

So You (Don't Particularly)Want to Become A Farmer

This is a great article, for all you who might be married to someone that is catching farming fever, or might have caught it yourself. You should know, that this often starts out with liking the best of food on your table....and then comes the garden..... and after a few years the thought of really fresh farm eggs - yolks almost orange - becomes just a little too tempting. That is about where I am now.... and even thinking that a goat might be a possibility - they aren't any bigger than a good sized dog after all. Dangerous, dangerous thoughts.

More on Bicycle Trailers


We had a lot of fun this weekend with D&A down with the kids, and lots of fun conversation. One thing that D and I talked about a little was bicycle trailers, and how useful they could be if you wanted to make any kind of extended trip on a bicycle.

I was looking around on KSL Classifieds today and found this:

http://www.ksl.com/index.php?nid=218&ad=9392527&lpid=&cat=191

This looks like a permanent ad that he runs (www.DluxFab.com click on Bike Trailers). There are a variety of designs offered, with prices from $200 to $300. Locally manufactured.

For those of us that don't know when to quit, just seeing how they are built might be enough of a blueprint to get one built.

Grafting Designer Fruit Trees

A great article. I've been looking for a good article on grafting fruit trees for some time. I've never tried this yet, but I think I will be working on it this summer.

The author (Jackie Gray) shows you not only how to do the grafting, but how to get the root stock (plant seeds of trees that you like) for free, how to get scion stock (the part that you graft on and actually get the fruit from).

Have fun. I'll let you know how my experiments go.
